Looking in early 1970 issues of soaring, one finds a few ads for used
2-33As, a typical one:

SCHWEIZER 2-33A, standard instruments and one vario.
1968 model, less than 250 hours. Firm price $4950.

I haven't found a single used one selling for over $6000, and they
only started making them in '67. How about this ad:

SCHWEIZER 2-32, trailer, oxygen, BEI omni, BEI 990 radio,
J-8 horizon, airspeed, altimeter, turn & bank, Winter vario,
Cook T.E. vario &audio, electric T&B, Cook compass,
accelerometer, clock, temperature gauge, exide battery, and
other extras making N2450W the most sophisticated
in the country. Less than 40 hrs time, in perfect condition.
Cost $16,000; will sell for $11,950 or best offer.

And, finally, quoting from the 2-33 introductory article in the
February '67 Soaring:

Price for the standard ATC'd sailplane is $5,250 F.O.B. Elmira,
New York.

That would have been something like 66% inflation per annum. Sounds
like you got ripped off...
